Description of problem:
"""
api = API(url=self.url,
          kerberos=True,
          ca_file=self.ca_file,
          filter=True
      )

name = "some-vm-name"
vm = api.vms.get(name)
vm2 = api.vms.get(name)
vm3 = api.vms.get(name)
"""

quite often(subjective, no real measurement) in can happen that one or more of vm, vm2 or vm3 contain None but others have the desired vm object.


Version-Release number of selected component (if applicable):
rpm -qa "*ovirt*"
ovirt-engine-sdk-java-javadoc-3.5.1.0-1.fc22.noarch
libgovirt-0.3.3-1.fc22.x86_64
ovirt-engine-sdk-python-3.6.0.3-1.fc22.noarch
ovirt-engine-cli-3.6.0.2-1.fc22.noarch

server is: Version 3.6.1-0.2.el6


How reproducible:
not always

Steps to Reproduce:
1. see description


Actual results:
api.vms.get(name) sometimes returns None when the vm exists

Expected results:
api.vms.get(name) always returns vm object if the vm exists

Additional info:
If it returns None because of some external error(network, auth issue). Then the API should raise an exception and not return None.
